This one was a bit harder as the previous record was for a much smaller C194.

And thank you for clarifying parts of your search strategy. Was hoping for something I could use on the outside of the UI for msieveGPU and CADO but it seems that would involve a lot of coding work  above my pay grade. I’ll keep playing around with standard msieveGPU. I’ve got more HCN GNFS jobs if anyone is interested. C193 and two C194, all have completed due diligence via ECM.

Base2 extension Cunninghams
The Cunningham "SmallerbutNeeded" list currently consists of the following three composites, all from the recently added base2 extension. They are the only remaining Cunningham composites below 211 digits.

As to the proposed poly search, I will start on c202 2,2822M with CADO using the following: P 4500000 admin 5e6 admax 6e6 adrange 840 incr 210 nq 15625 nrkeep 200 roeffort 60 soeffort 40 Any advice on my choice of poly search parameters welcome. This isn’t my first CADO search but I’m still struggling to find a balance between a thorough search and the speed to produce useful results faster than say a month for a c193 split between two machines. Other than to buy more/better machines of course.
